MEANS FOR JOURNALING A VERTICAL SHAFT.

Specification of Letters Patent.

Patented Sept. 25, 1906.

Application filed M y 7, 1906. Serial No- 315,629.

To It whmn it may concern;

Be it known that I, KARL LoHLE, a citizen of the Republic of Switzerland, residing at Zurich, Switzerland, have invented new and useful Improved Means for J ournaling Vertical Shafts, of which the following is a specification.

The object of the present invention is to provide means for journaling a vertical shaft. This eontrivance comprises a float which operates in a receptacle containing a liquid and which is intended to carry the shaft, guiding means, and a brake device which serve to respectively retain the shaft in the vertical position and exert a braking action 011 the shaft upon the latter being loaded down beyond a predetermined. limit.

In the accompanying drawings there is shown, by way of example, a device embodying my invention, in which Figure 1 is a vertical sectional elevation; and Fig. 2, a plan view, partly in horizontal section, on line A A of Fig. 1.

The vertical shaft or axle a is carried by means of the radiating bracket-arms b by the hollow float c, concentrically arranged about the shaft and having an annular form of rectangular cross-section. This float operates in a correspondingly annular trough (I, likewise concentrically arranged about the shaft, which latter is centered in thebushing h. In order to prevent the shaft from assuming an oblique position, there is provided on the fixed trough d a circular running-board 6, preferably of I-iron, upon the under face of which run the rollers f, secured to the bracketarms I). The rollers are pressed against the runway e by the up pressure of the float. By regulating the liquid-level in the trough the degree of pressure exerted by the rollers f can be regulated so that moments of tilting acting on the shaft will have no influence on the vertical position thereof.

If for any reason the shaft a is overloaded, the float 0 will dip deeper into the liquid,with the result that the brake-shoes g cooperate with the runway 6. These brake-shoes may .be secured directly to the radiating arms I) or to an auxiliary framework carried by these arms.

It is obvious that the runway e could also be secured to the arms 1) instead of to thetrough (Z, in which instance the rollers f and the brake-shoes 9 should be attached to the trough. I may also construct the walls of the trough (Z so that they serve as runway and brakeway.

Having now particularly described and ascertained the nature of the said invention and in what manner the same is to be performed, I declare that what I claim is 1. Means for journaling a vertical shaft comprising a liquid-containing receptacle, a float therein adapted to carry a vertical shaft, and means external of the receptacle for guiding said float.

2. Means for journaling a vertical shaft, comprising a trough, a liquid therein, a float in said liquid adapted to carry a vertical shaft, means for horizontally guiding said float, and means for braking down said shaft.

3. Means for journaling a vertical shaft, comprising means for centering the shaft, a liquid-containing annular trough, a float therein carrying the shaft, radiating arms on said shaft, rollers and brake-shoes on said arms, and a runway and brakeway on said trough, alternately cooperating with said runway and brakeway.

4. Means for journaling a vertical shaft, comprising means for centering the shaft, a liquid-containing annular trough, arranged concentrically about said shaft, a float in said trough carrying said shaft, radiating arms on said shaft, and guiding and braking means connected with said trough and said arms re spectively.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
